分享自用支付宝支付类 分享自用的支付宝支付类目前只封装了 订单查询以及app支付更多的支付 后期会集成异步主要商户订单号查询 并确定金额是否与数据库中一致以及判断该商户订单号是否处理过（谨记）个人觉得验签并不重要 有订单查询以及数据库订单验证就行了过多的就不介绍了 源码有注释 <?php /** * @author anderyly * @email admin@aaayun.cc * @link https://blog.aaayun.cc/ * @copyright Copyright (c) 2019 */ class AliPay { // 应用ID public $appId; // 私钥 public $privateKey; // 公钥 public $publicKey; // 异步地址 public $notify_url; // 同步地址 public $return_url; //返回数据格式 public $format = "json"; //版本 public $version = "1.0"; // 编码 public $charset = "UTF-8"; //签名类型 public $signType = "RSA2"; // 配置 public $config; // 网关 public $gatewayUrl = "https://openapi.alipay.com/gateway.do"; public function __construct($appid, $privateKey, $publicKey, $notify_url, $return_url) { $this->appId = $appid; $this->privateKey = $privateKey; $this->publicKey = $publicKey; $this->notify_url = $notify_url; $this->return_url = $return_url; $this->config = [ 'alipay_sdk' => 'alipay-sdk-php-20180705', 'app_id' => $this->appId, 'notify_url' => $this->notify_url, 'sign_type' => $this->signType, 'charset' => $this->charset, 'timestamp' => date('Y-m-d H:i:s', time()), 'version' => $this->version ]; } /** * app支付 * @param $out_trade_no 商户订单号 * @param $total_amount 金额 * @param $subject 标题 * @return arrray */ public function app($out_trade_no, $total_amount, $subject) { $method = 'alipay.trade.app.pay'; $config = $this->config; $config['method'] = $method; $biz = [ 'total_amount' => $total_amount, 'product_code' => 'QUICK_MSECURITY_PAY', 'subject' => $subject, 'out_trade_no' => $out_trade_no ]; $arr = [ 'subject' => $biz['subject'], 'out_trade_no' => $out_trade_no, 'total_amount' => $biz['total_amount'], 'appid' => $this->appId, 'notify_url' => $this->notify_url, 'sign_type' => $this->signType ]; $biz_content = json_encode($biz, JSON_UNESCAPED_UNICODE); $config['biz_content'] = $biz_content; ksort($config); $config['sign'] = $this->sign($config); $params_url = ''; foreach ($config as $k => $v) { if (!empty($v)) { $params_url .= $k .
